DALLAS – Phil Jackson walked off the court with a tight smile, shaking hands and accepting congratulations like he has after so many series-ending playoff games.

Never like this, though.

His team didn’t win; they were crushed. Swept, too.

And he wasn’t just heading to the offseason – he’s calling it a career, ending the most successful run by any coach in NBA history.

Jason Terry and the Dallas Mavericks ended Jackson’s tenure, and the Lakers’ reign as two-time champions, with a 122-86 victory Sunday. After two tight finishes and another game that was relatively close, the Mavs turned this one into a rout in the second quarter.

Things got ugly early in the fourth quarter, with vicious, frustration-fueled cheap shots by Lamar Odom and Andrew Bynum getting them ejected 45 seconds apart.
